Presently, OLED screens are manufactured by trained technicians in large high-tech factories. Now, however, scientists have managed to 3D print a flexible OLED display, paving the way for small businesses to one day be able to do the same thing.

Patients don't like getting needles, nor do clinicians like having to keep protein-based vaccines cold at all times. A new polymer wafer – which dissolves when placed under the tongue – could address both issues.

When a child receives a replacement heart valve, the device doesn't grow along with them. This means it will have to be surgically replaced, multiple times. Such may not be the case, however, with a new valve that's currently in development.

A number of hearing aids are now able to amplify one person's voice while filtering out distracting background voices. Well, it turns out that female tree frogs are able to perform a similar task, in order to hear the mating calls of males.

Astronomers have detected a strange signal coming from neutron stars that could be a new elementary particle. An unexplained excess of X-rays hints at axions, hypothetical “ghost” particles that could solve several long-standing physics puzzles.

Researchers have for the first time managed to use electricity to switch on magnetism in a material that’s normally non-magnetic. This could be a step towards making electronic components out of common materials that might not otherwise be suitable.

Once discarded, spongy polyurethane foam typically just ends up in landfills, where it takes up a lot of space. Thanks to a newly-developed process, however, it could soon be recycled into higher-quality rubbers and hard plastics.

The final results of a Phase 2b human trial into the efficacy of a new tuberculosis (TB) vaccine have been published, indicating safe long-term protection from the devastating disease in around half of the subjects vaccinated.

There is a lot to learn about Alzheimer’s and how it can be better treated. Scientists now have an inventive new tool with which to look into such matters, in the form of a transparent skull that allows them to peer into heads of mice.

​When he was an assistant professor at Princeton University, Michael McAlpine led the development of a 3D-printed bionic ear. Now an associate professor at the University of Minnesota, he has gone on to 3D-print a rudimentary bionic eye.

Researchers at the University of Minnesota have designed a silicone device, covered in 3D-printed neuronal stem cells, that can be implanted into a spinal injury. There it grows new connections between remaining nerves to let patients regain some motor control.

Various research institutes have already developed skin-applied electronics, that are simply adhered to the user's body. Researchers at the University of Minnesota, however, have taken a different approach. They've developed a method of 3D-printing custom electronics directly onto the skin.
